My invention rol-tes to improvements in' engines of the internal eonibnslinn type. and is of particular value in mi engine of the inu l tiple-f-,ylin der varie t \v The oliject of the invention is to improve `lthe construction of the `sri-culled intuire Pipe, whereby o proper quantity of gas will j always be provided to each cylinder.

One of the great dilliculties in engines of this character is to provide nn ellcient andv unii pipe 3.

Forni supply ol"I gos to nll of the cylinders. By in v iinpim'ement this diiliculty is prantenlly eliminated, as will hereinafter be seen.

lily invention ii-r enin'entioimlly illustrated in the accompanying drawing, which shows the apparat-us on n reduced seule und in sertion.

B having the return pipe 5 Asuitably snm ler in cross-sectionalcapocity than the pipe 3, vacuum is avoided. undy bymaking it sufficienti smaller a sufficient resistieneoor throttle e ectmay be provided t-.theirempte end of the pipe 34 to provide en oeeuxniLile-i tion of gas.

In an intake pipe-constructed iiter 'the ino'nner ofpipe 3, butfwithout-,thelreturn pipe' 5, it is obvious that on demand for as nem" the sup ly end, wou] -tend 'to Vrol: it e remote end o seid pipe,"with the resultihat cylinders to ing into Suid remoto end would not be as e eiontlyv fed. By'rny improved invention, however, o constant eirulatlonbeing maintained, ii uniform supply will always lie found in all parts of pipe 3..

It should be understood that my pnnyingdrnwing is purely conventional and tlnit no attempt has been mzrletoy showjtl'ie' proper proportions, since they would vvary- 2.
